upper roller bearing

1. The products are made of imported carbon compound material,giving a strong control force over the fibre, a more logic distribution of the frictional force,cutting off irregular abortives and reducing the defective yarns.
2. Replacing the SL-6825EA with the SL-6819A compressive upper roller bearing sheath is helpful to stabilize the drafting,adapting to the high temperature and high humidity spinning ambience and the problem of the traditional iron roller rusting has been thoroughly tackled..
3. Big friction coefficient, balanced and reliable transmission,good synchronism and identity,stable drafting,slipage prevention,reduced finished yarn body CVvalue,extended rubber ring service life.
4. Carbon fibre upper roller bearing can completely replace the original SL-6825EA in use.Main advantage of this seral bearing is a thorough elimination of the rusting problem with th "middle" roller and bringing the yarn quality upward.
5. The upper roller bearing of this series have several different outer diamters D:Φ25Φ25.2Φ25.6, etc. Recently we are offering a "plastic spray surfaced" middle iron roller upper roller spring to increase the surface friction coefficient,which is more helpful to bring the finished yarn quality upward.We would like draw the user' attention to this.
6. The radial play end of these serial upper roller bearing is 0.003~0.012mm, the axial end play is ≤0.060mm,radial runout tolerance is≤0.005mm.
7. The core shaft holding crosspiece and the surface of the big exterior circle are chrome-plated to strengthen the anti-rusting ability,furthermore, to avoid the twining of the waste down because of rusting,effectively stop waste down from entrance to the bearing's rolling lanes. It is more applicable to combine with the pneumatic cradle
